Description

Изобретение относитс  к силоизмерительной технике и может быть использовано дл  измерени  контактных давлений под подошвой фундамента. Известное устройство дл  измерени  давлени  на грунт, содержащее корпус, в котором расположен поршень, жидкость, помещенную в корпус, и манометр, не обеспечивает требуемой точности измерени  давлени  I . Наиболее близко к предлагаемому изобретению устройство дл  измерени  давле ни  на грунт, содержащее рабочую камеру с жидкостью, диафрагму, соединенную с нагрузочным элементом, и индикатор 2 К недостаткам такого устройства от носитс  низка  точность измерени . Цель изобретени  - повышение точноо ти измерени . Дл  этого в устройство введена измерительна  камера, вьтолненна  в виде заполненного жидкостью корпуса с диа- фрагмой, причем измерительна  камера сообщена с рабочей камерой, а индикатс расположен на диафрагме измерительной камеры. На чертеже изображено предлагаемое устройство дл  измерени  давлени  на грунт. Устройство включает заполненные жидкостью 1 рабочую камеру 2 с диафрагмой 3 и соединенную с ней трубопрсводом 4 измерительную камеру 5 в внде корпуса 6 с диафрагмой 7, кольцом 8 жесткости и жидкостью 1. Измер емое давление воспринимаетс  нагрузочным элек1ентом 9 с уплотнительным колы1-ом 1О. Прогиб диафрагмы 7 фиксируетс  индихатором 11. Вли ние температуры учитываетс  компенсационной камерой 12 с подпружиненным поршнем 13. С целью повьпиени  точности измерений и расшнр&ни  диапазона измер емых давлений предусмотрено ступенчатое изменение жесткости мембраны . путем установки кольца 8 жесткости с соответствук цим внутренним диаметром. Применение диафрагмы 3 позвол ет измер ть небольшие давле-The invention relates to load measuring technique and can be used to measure contact pressures under the base of a foundation. The known device for measuring pressure on the ground, comprising a housing in which a piston is located, a fluid placed in the housing and a pressure gauge, does not provide the required accuracy of pressure measurement I. Closest to the proposed invention is a device for measuring the pressure on the ground, which contains a working chamber with liquid, a diaphragm connected to the load element, and an indicator 2. To the disadvantages of such a device, the measurement accuracy is low. The purpose of the invention is to increase the measurement accuracy. For this purpose, a measuring chamber is inserted into the device, filled in the form of a housing filled with liquid with a diaphragm, the measuring chamber communicating with the working chamber, and the indicator is located on the diaphragm of the measuring chamber. The drawing shows the proposed device for measuring the pressure on the ground. The device includes a working chamber 2 filled with fluid 1 with diaphragm 3 and a measuring chamber 5 connected to it with a tube 4 in the housing 6 of the housing 6 with a diaphragm 7, ring 8 of rigidity and liquid 1. The measured pressure is sensed by the load element 9 with sealing colo 1 ohm. The deflection of the diaphragm 7 is fixed by an indicator 11. The effect of temperature is taken into account by the compensation chamber 12 with a spring-loaded piston 13. In order to improve the measurement accuracy and expansion and the range of measured pressures, a stepwise change in the rigidity of the membrane is provided. by fitting a ring 8 of stiffness with a corresponding internal diameter. The use of diaphragm 3 allows small pressure measurements.
